Get icon by file name (web part function)

This function obtains the extension of a file and returns a icon of Image gallery.

This stuff is very useful on custom WebParts to organize documents.

public static string GetIconByName(string myItemName)

{

string extension = string.Empty;

char[] arr = myItemName.ToCharArray();

int index=0;

for(int i = 0; i <>

if(arr[i]=='.')

index=i;

for(int j = index+1; j <>

extension+=arr[j];

if(File.Exists(Path.Combine(SPUtility.GetGenericSetupPath(@"template\images"),

string.Concat("IC", extension.ToUpper(), ".GIF"))))

return string.Concat("IC",

extension.ToUpper(), ".GIF");

else

{

return "ICgen.GIF";

}

}
